Marc Andreessen's "Guide to career planning"[1] is a much better piece for almost everyone. My takeaways were:
1) You probably won't be the best in your field. Aim for top 25% in two or more (disparate) fields and becoming the best at the intersection of those is achievable. (This is actually advice from Scott Adams that Andressen quotes)
2) Better to be a small fish in a big pond.
